Volum Rendrer

Hi I'm working on a project where we need a Volum Rendrer. We are using OpenGL and Coin with SoQT. But we are looking for a Volum Rendrer, that dos not cost to much. We know about Sim-Voleon. This is to expensive. No open source.

Also try a search on Google if you have not already. I tried searching for Volume Renderers and got a lot of seemingly relevant results, but as Bubba pointed out, they may not be exactly what you are looking for.
